1990 k5 blazer ?

[Rally Smith]

Hey Mark, I found the thread with all of the bins you have there. I'm not sure which bin I need. Any suggestions on which I should use?

Thanks,

Rick

ASDU for auto and ASDX for manual.

Thanks man.

O.k. the guy selling this Blazer says that it's a crate motor. How big of a problem will it be to run vortec heads on a stock .bin?

[EagleMark]

Depends on what motor was in the crate?

They will all run, but none well on stock chip.

Well I'm going to look at it tomorrow and I will see if I can find some info off the engine and heads to be sure of what the heck it is. Any particular's that I should look for other than casting numbers?

Build sheet with cam specs.

Good buying point is it will never run properly, get good milage, put out power or pass emmissions without being tuned which costs about $500... as you walk away stop and ask "So what's the lowest you'll take?"
